The Steam icon on the Windows 7 taskbar still shows odd colours, wheh logging on the icon has a yellow background, when downloading the background is green but never shows that th e download is complete. This problem actually started during the last beta version and was never fixed.

I am still waiting for the option to have steam event notifications not alt tab games or have them go in the overlay or something. I love my events, but when in the middle of battle nothing is worse than getting minimized.

Someone just started chatting to me in Steam, and their chat window didn't show up in the Windows 7 taskbar. Or as a new tab in the current chat window. I had to open the friends list myself and click on his name to read what it said.

In hindsight it might have been hiding behind Firefox and I could've seen it that way, but it definitely wasn't showing up in the taskbar until I manually opened a chat window with the guy.

This is after combining 2 other chat windows into one. It might be related.
